Original Description

Large, robust; low sinistral trochospire, tight. Equatorial outline oval, barely lobate; lateral outline equally biconvex. Chambers angular-truncate, closely appressed, 4! in final whorl; increase moderate. Dorsal view: chambers longer concentrically, flat; sutures flush; last intercameral suture directed and curved posteriorly, limbate; other features obscured by thickening. Ventral view: chambers moderately inflated; intercameral sutures radial, narrow but deeply incised, meet at closed umbilicus. Lateral view: keeled periphery, very thick on early chambers of final whorl; dorsal face slightly concave; ventral face concave adjacent to periphery, inflecting to weakly convex, continuing to umbilical shoulder which covers umbilicus; aperture an umbilical--extraumbilical interiomarginal low slit, slightly higher near periphery; keel distinctly flexed axially. Wall finely and densely perforate, smooth, but heavily encrusted.

Size:
Length 650 µm; width 565 µm; height 320 µm
